Title: Improvements in or relating to fire extinguishing apparatus
IPC: A62C13/70
Filed: 1938-03-02
Abstract: 494,878. Fire - extinguishers. AMERICA - LAFRANCE - FOAMITE CORPORATION. March 2,1938, No. 6557. Convention date, April 9, 1937. [Class 47 (ii)] Relates to extinguishers in which liquid is expelled from an outer container by gas released from a bottle held within the container, and consists in automatic means for regulating the discharge of gas from the bottle to compensate for variations of pressure therein. The gas bottle 5 is carried by a sleeve 10 which is slidable on a boss 11 formed within the cover member 4 of the outer container. The boss carries a piercer 13 comprising a reduced stem 15 and an enlarged, bevelled, cutting head 14. The discharge passage 18 of the bottle is sealed by a disc 6 clamped in place by a plug 8. The discharge bore 17 of the plug is of smaller diameter than the bore 18. When the extinguisher is inverted, the sleeve 10 slides on the boss 11 so that the piercer perforates the disc 6. If the pressure in the bottle is high, the reaction of the escaping gas forces the bottle upwardly, so that the piercer head 14 partly obturates the narrower bore 17. If the pressure is low, or as it falls with discharge of the gas, the bottle remains in or returns to its lowest position, so that the head 14 occupies the wider bore 18. The bottle is provided with a discharge tube 9 so that gas only is discharged.

Title: Rotary loop-taker mechanism for sewing machines
IPC: D05B71/02
Filed: 1941-05-23
Abstract: 550,284. Sewing-machines. FAIRWEATHER, W: C. (Singer Manufacturing Co.). May 23, 1941, No. 6622. [Class 112] A vertical hook shaft 24 is mounted m ball bearings 27, 28 in the upper 29 and median 31 levels of a chambered casing 30 mounted upon a reduced portion 41 of a fixed sleeve 42 and adjustably secured to the machine frame by a screw 47. The shaft is hollow and surrounds a fixed wick-filled tube 67. The shaft is rotated by a skew wheel gearing with a pinion 54 and carries an eccentric 57 which, through a pitman 58 and lever 60, operates an arm 63 carrying a finger 65 by which the bobbin case is given a slight loop-freeing movement. The lower chamber 89 is filled with oil into which the skew wheel dips. Oil lifted by this wheel falls on shelf 78 and soaks into a porous filling 82. Thence oil is conducted by wick fillings 81, 75, 76 and 77 to the bobbin case race way. The amount of this oil flow is regulated by varying the pressure on the filling 82 imposed by a part 83 screwed at 84 into the casing. Oil passing upwards between the fixed tube 67 and the interior of the shaft 24 is discharged through raidal holes in the skew pinion and a radical hole leading to the surface of the eccentric 57. The chambers of the casing 30 are closed by a cover plate 37. Specifications 459,033 and 546,163 are referred to.
Patent GB-596982-A (GB)
Title: Improvements in or relating to the removal of wax from mineral oils, tars, distillation or transformation products thereof, or similar products
IPC: C10G73/06
Filed: 1945-03-16
Abstract: <PICT:0596982/III/1> In a process of removing wax from a mineral oil, tar, distillation or transformation product thereof or similar product, preferably in presence of a solvent, the wax-bearing oil or oil solution is cooled by passing it in counter-current to cold dewaxed oil or oil solution in a heat exchanger system, and in order to maintain throughout the system as high a temperature differential as can be permitted without the wax being precipitated in a form unfavourable for its removal, part of the dewaxed oil cooling liquid after passing through the heat exchanger is chilled without mixing it with colder liquid and is then returned to the heat exchanger system. If desired, the wax-bearing oil or oil solution may be mixed with quantities of solvent at one or more positions of its path through the heat exchanger system.  The proportion of cooling liquid which is re-circulated may be such that a constant temperature difference obtains between the oil being cooled and the oil used as cooling liquid throughout the period of heat exchange, or it may be in excess of this amount so that the temperature difference decreases in the direction in which the oil being cooled is flowing.  The temperature difference may be 15 DEG C.  As shown in Fig. 1, wax-bearing oil from pipe 1 passes in succession through three heat exchangers 2, and in countercurrent to cold dewaxed oil.  Scraping machinery is provided for keeping the chilling surfaces free from precipitated wax.  The stock may be chilled from 50 DEG C to minus 15 DEG C.  From the last chiller 2, the oil passes to two direct ammonia expansion chillers 3 and is cooled to about -32 DEG C.  The wax is removed in the centrifuges 4 and discharged through pipe 5.  The dewaxed oil is pumped through pipe 9 and the heat exchangers 2.  Part of the dewaxed oil which has passed through to pipe 10 is returned through pipe 11, pump 12, a direct ammonia expansion chiller 13, and pipe 14 to the coldest end of the heat exchangers 2.  If desired the cooling liquid may be returned or withdrawn at other parts of the heat exchanger system 2 e.g., between the second and third of the series.  Instead of passing the liquid to be cooled through the heat exchanger system at a constant rate, the rate of flow may be successively increased by adding a solvent diluent in several successive steps in the course of the chilling e.g., between the first and second or second and third of the heat exchangers 2.  The diluent may be at the same temperature or 10 DEG -15 DEG C below the temperature of the wax bearing stock at the point of the chilling system where the diluent is introduced. The dewaxing may be carried out in two stages, the oily wax obtained in the first stage being washed in a second stage with an oil solvent.  The dilute oil solution from this stage may be used as diluent in the first stage.

Title: Improvements relating to nuclear reactor fuelling arrangements
IPC: G21C19/06
Filed: 1963-02-20
Abstract: 1,009,384. Fuelling reactors. ATOMIC ENERGY OF CANADA Ltd. Feb. 20, 1963 [Oct. 10, 1962], No. 6775/63. Heading G6C. In a fuelling arrangement for a reactor having horizontal fuel tubes and employing a pair of substantially similar machines as disclosed in Specification 1,009,381 coupled to opposite ends of the selected tube, each machine having a magazine and a ram, the machine coupled to the downstream end of the tube in relation to the flow of liquid coolant through the tube, has means for producing an auxiliary stream of liquid coolant to flow from the machine into the tube so as to inhibit flow of hot coolant from the tube into the machine. The auxiliary stream is at a lower temperature than the main hot coolant flow and protects the machine from high thermal stresses which would occur if the main coolant entered therein. As shown, the end portion 15d of a reactor tube 15 is received in the snout 13 of a fuelling machine 9 having a magazine 18 rotatable by a shaft 16. A liner 15e forms an annular space 23 in the tube 15, the main hot coolant flow A from the reactor passing into the space 23 through ports 24 and leaving through a connection 22 leading to a main heat exchanger H. To ensure that most of the flow A passes through the ports 24 and does not enter the machine 9, an auxiliary flow B is produced in the machine to leave through the snout 13 and mingle with the flow A, the flow B passing with the flow A through the ports 24 and connection 22. The flow B is supplied to the machine 9 through a conduit 25b and manifold 25 and issues through jets 25a, flow B being much smaller in volume and velocity than flow A. After passing through the heat exchanger H the coolant returns to the upstream end of the tube 15 through a header 30. As shown in Fig. 5 the machine 9<SP>1</SP> at the upstream end of the tube 15 also supplies an auxiliary flow B and the tube 15 works in conjunction with an adjacent tube 15<SP>1</SP>, the upstream and downstream ends of the tube 15<SP>1</SP> being reversed in comparison with tube 15. The machines 9, 9<SP>1</SP> are supplied with coolant through conduits 31, 31<SP>1</SP>, coolers 33, 33<SP>1</SP> and pumps P2, P2<SP>1</SP>. Specifications 1,009,382 and 1,009,383 also are referred to.

Title: Improvements in and relating to gyratory crushers
IPC: B02C2/06
Filed: 1920-03-08
Abstract: 163,170. Mond, A., (Traylor Engineering & Manufacturing Co.). March 8, 1920. Crushers with gyrating heads.-Relates to gyratory crushers of the kind in which the shaft carrying the crushing-cone is moved in an orbital path and lubrication is effected by means of a pump in an oilchamber operated by the movement of the eccentric in an oil-chamber beneath the shaft. The pump is connected to the shaft or to a cylindrical sleeve thereon so as to be operated by the orbital movement of the shaft of sleeve. The cylindrical part or sleeve 5, which is keyed to the cylindrical part 1<b> of the shaft 1 of the crushing-cone 2, and has a flared upper end 5a to receive the tapered part 1<a> of the shaft, projects beyond the lower end of the shaft and is closed at its lower end so as to form an oil-chamber 5<c>. The eccentric sleeve 6. which is mounted in the bearing-member 7 carried by the cylindrical part 8<a> of the crusher frame 8 projects above the sleeve 5 and is flared at its upper end to correspond to the portion 1<a> of the shaft. The upper end of the sleeve 6 projects into an annular recess in the lower part of the cone 2, and a bevel-wheel 10 at the lower end of the sleeve gears with a wheel 11 on the driving- shaft 12. A casing 14 detachably secured to the lower end of the sleeve 5 contains the gears 15. 16 of a gear pump, and the shaft of the wheel 16 projects through the bottom of the casing and carries a wheel 17 which gears with a stationary rack 18 on the removable cover-member 19. Oil passes from the annular oil chamber 20a in the removable cover-plate 20 by a port a into the chamber 21 beneath the casing 14, and through an opening 21a in the bottom of the casing 14 to the pump which forces it through an opening 21<b> into the space within the sleeve 5 beneath the end of the shaft 1. Ports 6<x> lead the oil which overflows at the top of the sleeve into an annular chamber 7<x> in the bearing-sleeve 7, whence it passes down between the outer surface of the eccentric and the bearing-sleeve 7, one of these parts being provided with grooves. Oil reaching the bottom of the grooves is thrown outwards by centrifugal force over the wheel 10. Surplus oil passes from the channel 7<x> by a port x and a pipe 21<1> to a chamber 22 encircling the bearing 13 of the driving-shaft 12, whence it passes by ports 13<a> to the bearing 13 and by ports a<1> to the chamber 20<a>. To enable the crusher to operate in either direction two sets of ports are provided, one set of which may be plugged up. The sleeve between the shaft and the eccentric may be dispensed with as shown in Fig. 2, the pump casing 14<x> then being secured directly to the bottom of the crusher shaft 1<y> which is provided with a vertical oil-passage y with transverse passages y' leading to the eccentric bearing and to the oil-channel at the top.
